4
Precision Average the number of relevant documents in the top 5 for a given query Average over all queries

5
Mean Average Precision For each relevant document in the top 10, find the precision up until its rank for a given query Sum the precisions and normalize by the known relevant documents Average over all queries

6
Normalized Discounted Cumulative Gain Normalize the Discounted Cumulative Gain by the Ideal Discounted Cumulative Gain for a given query Average over all queries

7
Normalized Discounted Cumulative Gain Discounted Cumulative Gain – Give more emphasis to relevant documents by using 2 relevance – Give more emphasis to earlier ranks by using a logarithmic reduction factor – Sums over top 5 Ideal Discounted Cumulative Gain – Same as DCG by sorts by relevance
